ROAD-ENGINE.

SPECIFICATION forming part of Letters Patent No. 270,999, dated January 23, 1883.

Application filed December 4. 1882.

To all whom it may concern:

Be it known that we, EDWARD J. TAYLOR, of Alaska. in the county of Mineral and State of \Vest Virginia, and CHARLES L. PAGEN- HART, of Boyceville, in the county of Clarke and State of Virginia, have invented certain new and useful Improvements in Road -Engines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to'the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of the device; Fig.2, a top view; Fig. 3, a transverse section on the line a: as, Fig. 2.

This invention relates to improvements in road -eugines, more especially to that class which have their boilers suspended or oscillatorv.

The object of the invention is to arrange the mechanism so that the boiler can be adjusted easily or balanced while the machinery is at work without in any way interfering with the action of the latter, and without having the ease of adjustment affected by the pressure of the moving machinery.

The invention consists primarily in aroadengine having its boiler suspended within its frame by trunnions and having the drivingshaft passing in suchtruunions, and, incombination therewith, positive means for adj usting or balancing the boiler.

In the annexed drawings, the letter A indicates theroad-engine frame, supported on the wheels B O. The side rails, a, of the frame are curved at a to allow the wheels B free movement in turning the engine. To these side rails, a, are secured the boiler supporting standards or side pieces, D, consisting of legs d d, extending from each end of the frame and meeting at the apices (1 at which points the standards are provided with bearings d to receive the trunnions ofthe oscillatory boiler F. 011 top of this boiler is placed the machinery for driving the engine and operating the various machines with which it may be used.

(No model.)

The bed-plate G is formed with a troughlike body, g, to accommodate the crank and pitman, the cross-heads guides g g, and the circular end 9 the last forming one of the cylinder-heads. This bed-plate G is secured by its bottom hearing or fastening flange, 9 to the boiler just in front of the line of the firebox, as shown, and from the bed-plate in the same vertical plane with this bearing extend the trunnions E. The trunnions as well as the hearing are preferably made in one piece with the bed-plate; but they may be made separate and connected thereto. These trunnions E are curved outwardly and upwardly, as seen at e, from the bed-plate, and terminate in the journal ends 0 which are reduced at 0 where they enter the bearings 01 and have the longitudinal bores 0 The upper portions or halves of these trunnions are removable, and in the bores e are passed the ends h of the driving-shaft H, which also works in bearings h h upon the tops of the sides of the bedplate G.

At one end the driving-shaft is provided with a device for connection with the running-gear of the engine and at the other with the band: wheel for connection with the thrasher or other machine which is to be operated. The shaft is also provided with the eccentrics for operating the valve-stem, the latter having connected with it the usual reversing mechanism. At its middle, within the trough of the bedplate G, this shaft H isformed with thecrank k attached to which is the pitman I, connecting with the rod is of the piston which works within the cylinder K.

To one side of the bed-plate G is placed the pump L, which supplies water to the boiler through the pipes l 5 from the tank M, and is operated by the piston-rod is through the connection m. y

- The construction thus described forms a road-engine in which the boiler does not freely oscillatethat is, does not automatically level or adjust itself, because it is hung so that one end (the front) is heavier than the other. The boiler therefore I is one for which positive means of adjustment are to be used, and the mechanism already set forth is specially devised so as to allow of a positive adjustment without any interference with the operative machinery, so that this may be working and the boiler adjusted as desired. The boiler swings freely on its trunnions about the shaft, and the latter turns freely within the trunnions as the machinery works. In this way they turn or move independently. The shaft has a long bearing in the trunnions, as well as a bearing on the bed-plate, and the trunnions not only forming bearings for the shaft,

but in their turn resting in the frame-bearin gs, the whole weight is transferred to these and friction between the shaft and trunnions is relieved, allowing full freedom of movement.

Atone end of the hoilerF is located the device for positively adjusting it. Attached to or made with the leg at of one standard D is a threaded lug, n, and at one corner of the boiler'is a bracket, n, having the perforation or unthreaded hole of. Through this perforation freely passes a threaded bolt, N, the threaded lower end of which engages and works within the threaded lug 12. As the rod N is turned down within the lug it its head n bears upon the bracket 92, and thus draws that end of the boiler down against the overbalance of the other end. As the rod is withdrawn from the lug that end of the boiler is released, and the other and heavier end swings down. In this way the boiler can be oscillated upon its trunnions by the rod N, and adjusted as the circumstances may require,

. either in traveling or in leveling the boiler for work when the engine is stationary.

If desired, the device may be arranged so as to have the boiler automatically adjustable, and no positive adjusting device he used, by

simply changing the position of the bed-plate with the trunnions and shaft, so as to balance theboiler. In this arrangement, as well as the other,the relation of the trunnions and driving-shaft is valuable. The machinery being secured to. the boiler and oscillating with it,

there are no connections to be affected by the movements of the boiler, as the latter automatically adjusts itself in traveling, and the trunnions turn freely above the shaft without disturbing the machinery in like manner as they turn when the boiler is adjusted positively.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-

1. In a road-engine, the supporting-frame provided with hearings, in combination with the boiler within the frame, and provided with hollow trunnions, and the driving-shaft passing within said trunnions, the latter resting within the frame-bearings, and these supporting the whole weight, as set forth.

provided with hollow trunnions, in eombinal tion with thedriving-shaft passing Within such trunnions, as set forth.

3. The frame, A having bearings (P, in combination with theboiler F, provided with the hollow trunnions E, and the shaft H, passing within said trunnions, as set forth.

4. The oscillatory boiler F, provided with the bracket, 12, and the hollow trunnions E, the driving-shaft H, passing within said trunnions, and the frame A, having the lug n, in combination with the rod N, all constructed and arranged as and for the purpose set forth.

In testimony that we claim the foregoing as our own we affix our signatures in presence of two witnesses.
